After installing the Firefox 2 release candidate with its super-handy built-in spell-checker a couple of weeks ago, I whinged about not being able to edit the dictionary - but you can!

Firefox add-on developer Eric writes in to point out you can add a word marked as a typo to the dictionary by simply right-clicking and choosing - you guessed it - "Add to Dictionary" from the context menu. Nice! Thanks, Eric!— Gina Trapani
